John just came back from a camping trip and noticed a bull's-eye-shaped skin rash on his arm. John probably have lyme disease.
An infection with bacteria causes Lyme disease. When a blacklegged tick, sometimes referred to as a deer tick, bites you and remains attached for 36 to 48 hours, you become infected. You probably won't develop the infection if you remove the tick within 48 hours.
Some Lyme rashes have a bull's-eye appearance with circles surrounding the centre. However, the majority are 2 inches or larger, spherical, and crimson. Over several days, the rash gradually gets worse. It may expand to a width of roughly 12 inches. Even though it may be warm to the touch, it rarely hurts or itches. Lyme can manifest itself anywhere on your body.
